It's a bad move from Telltale to use characters from the comic since you know (or at least the ones that read the comic know) that they can't die, they have to leave.
probably worse for the non readers since they dont understand why their choice to save Sean was mooted or why no matter how nice they are to Lily she's out too...Im sure Sean's death was the spark to the 'no choices' fire
